Multiple Processors for the Real World
A PC with multiple CPUs is no big thing – dual processor Pentiums were available ten years ago. And it’s not news that four, eight or more processors can be shoehorned into a single enclosure. Multi-processor servers have been running networks for quite a while. The New Big Thing is multiple processor chips.
Both Intel and AMD are shipping dual core processors – processors with two CPUs on a single chip. Thanks to tremendous reductions in feature size (Intel manufactures on a .65nm process), many more transistors can fit into a reasonably sized package. Improvements in metallurgy also means that the cost of copper interconnects in the chips have dropped tremendously.
